HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 559,807, dated April28, 1896. Application filed July 17, 1895. `Serial No. 556,279. (Nomodel.)

To @ZZ 10700772, z'f muy 0077.067172.`

ie it known that I, WILLIAM I-I. PAGE, ot Basic City, county of Augusta,State of Virginia, have invented certain new and useful Improvements inHeating Apparatus, of which the following' is a specification, referencebeing had to the accompanying drawings.

The object of my invention is to provide a heat-radiating drum for usein connection with stoves, furnaces, or other initial heaters soconstructed that the maximum heatradiating surface will be obtained inthe smallest possible compass and that a free circulation of air overthe heated surface will be provided for.

In the accompanying drawings, Figure I is a perspective view of my drum,showing the envelop partially broken away. Fig. II is a central verticalsection. Fig. III is a transverse section on the line 3 3 of Fig. I.Fig. IV is a view of the envelop detached. Fig. V is a view of a modiiedform of my drum.

Referring to the figures on the drawings, l :indicates the body part ofmy drum pierced by diametrical air-lines d and al, extendingsubstantially to the top and bottom of the body part and defining aplurality of sector shape longitudinal s1noke-iiues 5, which latter openat their opposite ends into terminal domes (i and 7, formed by thecollars 8 and caps 9. It is obvious that this general design may beobtained by any suitable construction, the several parts being cast inthe most convenient forms and united in the usual manner. In thedrawings, however, is illustrated a construction which I have found tobe simple, eflicient, and inexpensive. In this preferred constructionthe smoke-fines are formed, respectively, of a plate 10 bent at rightangles and constituting a partition-wall between the smoke and air iiuesand having their lap edges ll bent to conform to the cylindrical bodypart.l The exterior plates l2 constitute the exteriorwalls of thesmoketlues and are clamped to the lap edges of the plates 10 by boltspassing through longitudinal brace-rods 13 within theinterior andsimilar rods Il upon the exterior of the smoketlues.

The plates 12 extend beyond the edges of the collars 8 andare clampedthereto by the curved end brace-rods 13 and le, secured to the collars 8by terminal bolts 15, which pass through the rods 13a, collars S, andthe eX- tremities of the rods 13 and are provided with nuts IG upontheir extremities, as usual..

The exterior plates l2 are provided with notched corners 17 for thereception of the bolts l5. By this means it is unnecessary to entirelyremove the end brace-rods when it is desired to remove the exteriorplates l2 for cleaning, as will hereinafter more clearly appear.

The air-lines are closed at their top and bottorn by frames IS, whichiit closely between the plates l0, and are securely clamped between themby bolts i9, passing through the adjacent walls of the smoke-fines tosecure the parts against displacement and seal the joints without theintervention of solder or similar seals.

The plates l0 preferably extend somewhat beyond the frames 1S to form asoot-receptacle 20, which serves to collect the soot and'prevent itsaccumulating upon the sides of the air-dues.

The caps are formed, as shown, with a conical part and a cylindricalcontinuation thereof adapted to iitin or around the adjacent scctions ofa stovepipe through which the prod ucts of combustion pass from a stoveor initial heater. i

The periineters of the caps project a considerable distance beyond thebody part and are preferably turned down upon the annular flanges 2l ofthe collars S. The purpose of these projecting perimeters is to securelyretain between them a spirally or otherwise tinted envelop, the tlutingsof which extend beyond the edges of the caps and open into theatmosphere.

Supposing my drum to constitute a section of the escape flue or pipethrough which the products of combustion pass, it will be observed thatthe heated products will pass through the smoke-dues of the drum and outat its upper end. The heatingot the drum will cause the atmosphere ofthe room to pass into the flutes of the envelop at their lower ends andwill cause it to circulate over a part of the exterior surface of thebody part and IOO through the diametrical passages, escaping iinally atthe top of the iiutings upon the opposite side of the drum. Not onlywill a free circulation to the full capacity of the diametricalair-fines be maintained, but a constant circulation lwill be kept upthrough the iiutes adjacent to the exterior walls of the smoke-dues.

In the event of the accumulation oi' soot and the like within thesmoke-fines it is only necessary to remove the longitudinal bracerodsand loosen the bolts of the end bracerods, when, as will be apparent,the top and bottom edges of the plate l2 may be slipped from under thelast-named rods, the replacing of the plate being accomplished withequal facility after removal of the debris.

As I have hereinbefore mentioned, the details otl construction aresusceptible of wide variation. For instance, as shown in Fig. V, insteadof constructing the smoke-fines from a number of plates and bracing themwith lon-` gitudinal brace-rods they may be constructed of a singleplate bent to produce the required design, the adjacent edges of eachflue being seamed together and the various f'lues being retained intheir proper relative positions by the collars of the caps which in thisconstruction encircle the outside plates of the flues. I do nottherefore desire to limit myself to the details of construction hereinshown and described, but reserve the right to modify and vary them atwill within the scope of m5 invention.

Vhat I claim isl. A heating-drum, the body part of which is formed ofseparate longitudinal smoke- 'tlues open at their opposite ends anddefining` between their walls a diametric air-flue extending entirelythrough the body part and continuously from the top to the bottom of thebody part, the top and bottom of the airtlue being closed, substantiallyas specified.

2. The combination with a body part, of a drum composed of a pluralityof separate smoke-fines defining between their walls a plurality ofdiametric air-flues, the smoke- 'fiues and air-fines extendingcontinuously from the top to the bottom of the body part, and theair-fines extending entirely and unobstructedly through the same, capsupon the opposite end of the body part communieating with thesmoke-fines and having no communication with the air-flues,substantially as specified.

3. The combination with a drum having its body part composed ofseparatelongitudinal smoke-nues defining a diametric air-flue, thesmoke-fines and air-fine extending the entire length of the body part,the air-flue extending entirely through the body part transversely andhaving its top and bottom closed, of an envelop surrounding said drumand communicating with the exterior atmosphere and with the air-fines,whereby the air is caused to enter the bottom of the envelop, tocirculate through the air-flue of the drum and to finally escape fromthe top of the envelop at the opposite side of the drum, substantiallyas specified.

4. The combination with a drum, the body part of which is composed of aplurality of separate smoke-fines defining a diametric airfiuecoextensive with the smoke-fines and extending entirely through the bodypart, of an envelop surrounding said drum and provided with spiralflutings communicating with the exterior atmosphere and with theair-ilue and traversing the exterior wall of one or more of thesmoke-flues, substantially as specified.

5. The combination with a drum having a plurality of longitudinalsmoke-fines defining a plurality of air-iiues extending entirely through the drum, oi' projecting caps from the opposite ends of the drum,and an envelop confined between the perimeters of said caps and havingflutings projecting beyond the edges of the caps opening into theatmosphere and communicating with the air-fines, through the drum,substantially as specified.

G. In a heating-drum, the combination with terminal collars andbrace-rods secured at their opposite ends to their collars, andsmokefines composed of a plurality of plates secured to said brace-rods,substantially as specified.

7. In aheating-drum, the combiifiation with terminal caps, of aplurality of smoke-'fines secured at their opposite ends, respectivelyto the caps and separated to define diametric air-fines extendingentirely through the drum and longitudinally coextensivc with thesmoke-fines, substantially as specified.

S. In a heating-drum, the combination with the collars, top and bottomframes I8 and separate longitudinal smoke-flues, of means for securingthe frames 18 to the collars, and mea'ns for clamping the smoke-finesagainst the sides of the frames I8, substantially as specified.

9. A heating-drum having a plurality of airlues provided, respectivelywith separate, independent, exterior plates, substantially as specified.

l0. In a drum, the combination with separate longitudinal smoke-fines,of a frame 1S secured between the smoke-lines slightly below their ends,the extremities of the smokeilues and the frames 1S constituting asootreceptacle, substantially as specified.
